Well, now that I have my airbox setup dialed in, I am going to recheck some even bigger mains and some K2 jet needles. I think it might need to be richer up above 7k rpm and not any richer down lower. K2's are thicker all the way down from my K9's I am running now. A couple of more tests and then I will be set up!

My poor landlord thinks his CRF450 is going to out run my airhead now that he has it geared to go 100mph. When he had it geared to go 85, he could barely out pull me until I shifted to second at around 65mph (meanwhile he had gone through at least three gears) and then I would leave him behind (as far as the engines are concerned!). He had five gears inside of two of mine. Now its three since I shift into fourth around 105. Now I am going to smoke him from the get go!
